Ashley Hebert and J.P.

It may have looked like a perfect proposal on the finale of The Bachelorette, but the newly engaged couple admits that there's a moment viewers didn't see.

"I went through this whole long speech and I thought it went really well and when it was her turn to speak ... I don't know what came out [of her mouth]. It made no sense," J.P. tells TVGuide.com. "It was really adorable." Ashley adds, "I'll be sure nobody ever sees that!"

 Although Ashley and J.P. have kept their relationship a secret since they finished filming, they spent many weekends together in solitary confinement learning each other's quirks.

"I now know she's completely ADD ... it's hard to keep up with, but it's what I love about her," J.P. says. "Her little idiosyncrasies are what make her special."
